a tremendous amount
about using and understanding the elecraft radios. Thanks Don!

Dave,
Yes, you should suspect U5 (or one
. If not, should I assume that the MCU is bad because it
always reads high?
Many thanks to anyone willing to wade through all this!

Hello and Happy New Year to everyone.
I have owned K2 serial no. 3980 for about five years and it has worked
flawlessly. A couple of days ago it stopped tuning properly. Instead of
tuning across a signal, it now acts like a crystal controlled radio that tunes
in discrete steps of
Dave,
Yes, do check U5, but ignore the voltages on pins 1, 2 and 3 because
they are digital and the active state may not correspond with the
voltage measured with a DMM.
U5 pin 8 must have 5 volts DC for the chip to work - if that is not
true, stop (all other tests are futile).
Next monitor
